Application omni s, issn, saw No. 486,524 :com (ci. :4a-139') This invention relates to winding devices or machines, capable of wide general use and e896- cially adapted for winding Vand compacting material comprising a series or multiplicity of indil vidual strands, such as, for example, steel wool, My'improved device is especially well suited for winding and compacting surface treating elements, of the type disclosed in my copending application for Bumng and abrasive device, filed on July 7th, 1930, S. N. 465,916, now Patent Number 1,879,083 of Sept. 27, 1932, wherein it is desirable to produce a rotary and cylindrical abrasive element having spirally wound thereon steel wool nlaments, the filaments extending substantially circumferentiallv of the spool.

It is an object of my present invention to provide a simple but highly emcient device for wind ing continuous multi-strand ribbons of material,

i such as steel wool, and for compacting and tensioning the strands substantially uniformly and properly 'as they are wound upon the spool.

A further object isto provide a winding machine of the type described wherein provision is made for Apreventing slippage of the strands, niaments or other materialat the ends of thefroll and wherein simple means are provided for guiding the `multi-strand ribbon of material onto the roll.

Another object is to provide a device of the class described wherein the rolls may be quickly and efilciently formed and wherein the nnished rolls may be easily and quickly removed from the machine and a new spoolsubstituted.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with. the accompanying drawing. in which like reference characters refer to similar parte throughout the several views, and in which:-

l In the form of the invention illustrated, a suitable base is provided which may comprise spaced longitudinal bars 7 connected together in relation' at their terminal portionsl by means of Fig. 1 is a plan view of ali-embodiment of my transverse bars 8 and 9 respectively, said bars having up-turned vertical opposed ends in each instance constituting mounting brackets. The mounting bracket indicated as an entirety by the letter M at the left hand or forward end of 5 the machine is shorter than the; mounting bracket B at the rear of the machine and has secured across the vertical arms 8a a pair of spaced horizontal rods 10 on which a guiding carriage 11 is` slidably mounted for movement transversely of 10 the base of the machine. The guiding carriage disclosed, comprises a depending U-shaped frame 11 having a central handle lla'at the upper end thereof land having two pairs of axially aligned slide bearings 11b in the lower portions of the 15 arms of the -U. Carriage 11 has journaled therein a pair of vertically aligned rollers 12 and 13 respectively, at least one of which is preferably knurled. The upper roller 12 is provided with l trunnions 12a which work in vertical slots11`c 20 formed in the upperportions of the armsof the carriage 11 to permit upward displacement of the v roller for compensating for the thickness of the material to be wound.

Across the medial portion of the frame of the 25 machine is secured a standard 14 having a base 14a and a pair of vertical arms 1411v constituting brackets for the mounting of a winding spool; Arms 14h carry at their upper endsv suitable aligned bearings 14e. The winding spool S which 30 may comprise merely a cylinder of suitable material, such as wood, is preferably rotatably mounted in the arms of standard 14 inthe following mannerz- A pair of spool-engaging members 15 are pro- .35

vided, each comprising a stem or YshaftA 15a of proper diameter to be journaled in one ofthe bearings 14e, 'said stem carrying at the inner end thereof disk 15b which has inwardly pro- Jecting and circumferentially arranged prongs 15e adapted to be stuck into one end of the spool withstem- 15a disposed axially thereof. The two bearings 14c are spaced a suillcient distance apart to enable the spool-engaging elements to be retracted or released from the ends of the spool for removing the spool from my device. A pair of removable spacer elements 16 are provided, each disposed between one of the bearings 14o and one of the disks 15b of the adjacent yspool-engaging element. Spacer elements16 as 50 illustrated in Fig. 6 may comprise a-U-shaped 'member adapted to slide over a portion of the stem of the spool-engaging'element and an upstanding handle 16a. by which the spacers'may be readily removed upwardly. A crank 17 may 55 be fixed to the outer end of one of the stems 15a for rotating spool B, or obviously suitable means such as a pulley, sprocket or gear may be provided for connection with a'source of 5 power. Mounting bracket B at the rear or right hand end'of the machinek is provided with opposed vertical arms 9a which lhave secured acrossthe upper ends thereof a horizontal shaft' or pivot rod 19. Several series of upper and lower compacting and tensioning plates 20 and 21 are swingv ably mounted on shaft 19 and as shown, members 20 and 21 comprise arcuate plates having upturned outer ends and having diminished and twisted shank p'ortions 20a and 21a respectively which are disposed in vertical plan the ends of said shank portions carrying, if desired, hubs which surround pivot .shaft 19. Each pair or series comprisesanupperandalowerarmw and 21 respectively and are spaced from. the other series and from the vertical rarms ofbracket B K by suitable means, such as spacing sleeves 22,

*which surround shaft 19. l
